Admixture and population split models. (a) Population split model with three populations and without admixture. (b) Admixture model with two parental populations and one admixture event. (c) Admixture model with two parental populations and two admixture events. (d) Population split model with four populations and without admixture. (e) Admixture model with three parental populations and one admixture event. (f) Admixture model with three parental populations and two admixture events. In all models, the populations are allowed to have different effective sizes Ni, (i=1, 2, 3, H). The admixture and split events occurred at tadm1, tadm2 and tsplit generations ago.
